Section Quercus; -- A. Camus n° 176; -- hybrids with Q.lobata
and Q.engelmannii are put together under the name Q.x kinseliae ; -- the term "Q.dumosa"
has been applied to almost all the scrubby oaks of California; but 5 species have
been separated as true species : Q.turbinella, Q.john-tuckeri, Q.cornelius-mulleri, Q.berberidifolia and Q.pacifica;
the "true" Q.dumosa
is a quite rare species, restricted to low elevations; it differs from other scubby
oaks essentially in having large, visible hairs on the leaves undersides.
